Key Facts

  • Categorized as a Apollo-class Asteroid
  • Comparable in size to a school bus or smaller
  • Will pass within 11,755,308 km of Earth in 2035
  • Classified as a Near Earth Asteroid (NEA)
  • Not a Potentially Hazardous Object
  • See orbit simulation


2017 FT102 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2017 FT102 as a "Near Earth Asteroid" due to its orbit's proximity to Earth, but it is not considered potentially hazardous because computer simulations have not indicated any imminent likelihood of future collision.

2017 FT102 orbits the sun every 387 days (1.06 years), coming as close as 0.98 AU and reaching as far as 1.10 AU from the sun. Based on its brightness and the way it reflects light, 2017 FT102 is probably between 0.022 to 0.100 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.

Close Approaches

2017 FT102's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.

2017 FT102 has 6 close approaches predicted in the coming decades:

Date Distance from Earth (km) Velocity (km/s)
March 25, 2035 11,755,308 4.400
Nov. 28, 2035 16,900,441 2.631
Aug. 21, 2036 18,423,864 5.597

Images and Observations

2017 FT102's orbit is determined by observations dating back to March 25, 2017. It was last officially observed on April 3, 2017. The IAU Minor Planet Center records 79 observations used to determine its orbit.

Accessibility and Exploration

2017 FT102 can be reached with a journey of 362 days. This trajectory would require a delta-v of 4.46 km/s. To put this into perspective, the delta-v to launch a rocket to Low-Earth Orbit is 9.7 km/s. There are 837,318 potential trajectories and launch windows to this asteroid.
